STK1006 use jumper settings to enable switches that connect the peripheral IO pins of AP7000 to the STK1000 interfaces on the motherboard to daughter board connector. The STK1000 documentation explain how these STK1000 interfaces are used on the motherboard.
In addition to the jumpers documented below, all jumper settings for STK1002 applies.
The STK1006 is equipped with an 8-bit NAND flash. To enable the flash, two signals must be routed to GPIO signals: CS (chip select) and RDY (ready/busy signaling).
These two signals will be routed to AP7000 PB29 and PB30 (respectively) when the J20 pins 1 and 2 - and - 3 and 4 are connected with two jumpers.
The 16-bit NAND footprint shares RDY signal with the 8-bit flash (J20 pin 3-4). The 16-bit CS signal is connected to AP7000 PB16 when a jumper connects J20 pins 5 and 6.
